IMPROVEMENT IN WAGON-AXLES.

The Schedule referred to in these Letters Patent and making part 'of thesame.

To all whomit may concern v Be it known that we, GEORGE H. GLAD and JOHNCLBECKER, of Boston, in the county of Suolk and in the State ofMassachusetts, have invented certainnew and useful Improvements inWagon-Axles and l do hereby declare that the following is a full, clear,and

exact description thereof', reference being had to the accompanyingdrawing making a part of this speclcation, in which'- Figure 1 is a planview Of the upper side of an axle with the skein in place;

Figure 2 is a vertical longitudinal section of the saine, on the line a*:c of iig. l; and

Figure 3 is a top View of the axle-arlnwith the skein removed. A

Letters of like name and kind refer to like parts in each of thefigures. f

Our invention has for its object the lubrication of the journal of awagonfaxle in a thorough and easy manner; and

It consists, principally, in the construction of the, plug used forclosing the, upper end of the oil-c up, and

' in its combination with said cup, substantially as hereinafter shown.

It also consists in the construction of the oil-cup,

and in its combination with the grooved axle-arm, substantially as ishereinafter` shown, anclfor the purpose specified.

4 In the annexed drawing- A represents a inet-al axle, `having upon eachend an arm, B, and a nut, G, of usual construction.

.Resting upon and secured to the upper side of the axle A, between itsarms, is a bar Oi' wOOd,'D, upon each end of which is placed auoil-cup,E, havingthe general form shown in fig. 2, its upper half or cover, E',being detachable andsecured to said cup by means of the screws e passingthrough the former into the latter. v

Projecting downward and Outward from thelower side ofthe cup E is a lug,E", which terniinates'at the inner end of the axle-arm B, within the'face of the collar F, secured to and forming a part of the latter, and.serves to contain .an Opening, z, for the passage of oil from said cupto said arm.

From the outer end of said Opening z a half-round groove, G, extendsalong the arm B for a short dis tance, and then dividing the branches G,pass forward and downward in either direction until about Onehalf of aninch apart, and from thence extend Outward in slightly-diverging linesto apoint near the Outer end of said arm; e

By this arrangement Of the grooves the oil naturally flows outward andthoroughly oils the entire length of the bearing.

4Passimg; vertically downward through the'center of the cover E' of theoil-cnp is an opening, H, for the admission of Oil, which opening isprovided with a female-screw thread, and has fitted thereto a plug, I,having upon its periphery a corresponding male-screw thread, said plugbeing so closely fitted to said Opeliing as to make between them anearly air-tight joint. A small opening, ,'passing downward and inward,through the plug I, from a point alittle belowthe upper end of thescrew;thread, completes the Oiling devicesz the Operation of which is asfollows:

The cup being partly or entirely filled with oil, the plug is insertedand screwed downward, during which operation the air within .the cupescapes through' the openingA t while the upper end of said opening isabove the Cover, after which, there being no vent for said air, itbecomes compressed by the entrance within said cup of the lower end oflsaid plug, and forces outward the oil contained therein.

When it is desired to again lubricatethc axle-arm, the plug iswithdrawn' from the oil-cup until the u'pper end of the opening t' isabove the latter, when, by rcturnin g said plug to its place, a supplyof Oil is forced outward upon said axle-arrn`as before, the cup beingcapable Ot' a like operation until the Oil contained therein is entirelyexhausted.

In Order that dust or other abrading substances may be prevented fromentering upon the inner end ofthe axle-arm, a circular disk or.plate,'K, having a size corresponding to that of the inner end of thehub, is provided upon its inner fa'ceiwithv a recess which corresponds'in size and shape with thecollar F, so that, when said disk is placedagainst the outer faceof` said collar, the latter shall be whollycontained within said said-recess, as shown inlig. 2.

As thus constructed, the disk K, heilig attached to the inner end of theh'ub by means of screws, serves' not only to exclude from the bearingall dust and dirt, hut also to firmly lock in place within-the hub theskein L.

Having thus fully set forth the nature and merits of our invention,

` I. In combination with the Oil-cup EA and E', the

plug I, provided with the opening t', substantially as shown and for thepurpose set forth.

2. The Oilcup E and E', provided with the plug I and with the pertbratedlug E", in combination with the axle-arinB, provided with. theOil-grooves G, substantially as and for the purpose shown.

In testimony that we claim the foregoing, we'have hereunto set our handsthis 17thl day of J'une,w1870.
